- V-shaped seals are mainly divided into two types: non-cloth-clamped and with-cloth-clamped. The non-clamped type seal has good sealing performance at low pressure and poor sealing performance at high pressure; the cladded seal has poor sealing performance at low pressure and has better sealing performance at high pressure.
- V-shaped dense ring rings are generally used in plural. The more the number is used, the better the sealing performance, but the friction resistance increases. In order to improve the comprehensive performance of the V-shaped sealing ring, it is necessary to use pure rubber V-shaped dense
- The flexibility of the sealing ring also uses the rigidity of the fabric rubber V-shaped sealing ring, and the non-cloth type and the cloth type are often alternately assembled and used. When used for the piston seal of a double-acting cylinder, two sets of sealing rings must be used back to back.
